Michael Jackson has denied he has skin cancer and is still rehearsing for his forthcoming This is It shows. The Beat It singer's spokesperson, Dr Tohme Tohme, says he is in the "best of health" and doesn't have skin cancer, as recently reported. Tohme Tohme told the New York Daily News paper: "He is great. He in perfect health. He doesn't have any diseases whatsoever." Michael was said to be suffering from spots on his skin, cancer on his upper body and pre-cancerous cells on his face - thought to be linked to vitiligo, a condition he also suffers from. Despite his denial, Michael is reportedly under doctors' supervision, though he has defiantly pressed on with four times a week practices for his 50 date residency at London's O2 arena, which starts in June against their orders. A source told Britain's The People newspaper: "Michael is determined the show will go on. "He is determined his comeback shows will be the best they possibly can be for his loyal fans. The doctors finally came round to the idea, although they still want to keep a close eye on him." Michael is also said to be developing a new dance move to rival his famous Moonwalk of the 80s. Choreographer Kenny Ortega - who he worked with Michael on his 'Dangerous' and 'HIStory world tours - said: "He's working on something new, but I'm sworn to secrecy." Michael Jackson's residency at the O2 arena opens on July 8. Source:Tonight
